2 Installation This chapter describes how to install the SSC-5x86H. At first, the layout of SSC-5x86H is shown, and the unpacking information that you should be careful is described. The jumpers and switches setting for the SSC-5x86H's configuration, such as CPU type selection, system clock setting, and interrupt IRQ setting for serial ports and parallel port, are also included. 2.1 SSC-5x86H Ver.

2.2 Jumper Description You can change the SSC-5x86H's configuration by setting jumper switches on the board. The board's jumpers are preset at the factory. Under normal circumstances, you should not need to change the jumper settings. A jumper switch is closed (sometimes referred to as shorted with the plastic cap inserted over two pins of the jumper). A jumper is open with the plastic cap inserted over one or no pin(s) of the jumper. Figure 2.

2.3 CPU setting of SSC-5x86H Ver.C If you want to upgrade the CPU, you must do two things: 1. Set the jumpers for CPU type. 2. Adjust the jumpers setting for CPU speed.

Because right now in the market have several kind of CPUs using different voltage in core logic. For example the AMD offers 486DX2-66/80 and DX4-100/120 at 3.3V,Intel offers DX4-75/100 at 3.3V,and some Cyrix CPU will use 3.45V. CPU Voltage * +3.3V +3.45V JP13 2-3 1-2 (*) : default setting 2.4 Watch-Dog Timer The Watch-Dog Timer is enabled by reading port 443H.

2.5 DiskOnChip™Flash Disk The DiskOnChip Flash Disk Chip(DOC) is produced by M-Systems. The DOC have two models in market ED1102 (28-pin) and ED1202(32-pin). The two models DOC can be used in SSC-5x86H Ver.C board. Because the DOC is 100% compatible to hard disk and DOS. Customer don’t need any extra software utility to use it. It is just “plug and play”,easy and reliable. Right now the DOC is available in 1MB/2MB capacity, in the near future will have 4/8/16MB model soon.

4 AWARD BIOS Setup The SSC-5x86H uses the AWARD PCI/ISA BIOS for system configuration. The AWARD BIOS setup program is designed to provide maximum flexibility in configuring the system by offering various options which may be selected for end-user requirements. This chapter is written to assist you in the proper usage of these features. 4.1 Getting Start When powered on the system, the BIOS will enter the Power-OnSelf-Test routines.

4.2 Standard CMOS Setup The Standard CMOS Setup is used for basic system hardware configuration. Every time when you change any hardware configuration,for example memory size,you have to modify this setup again. Please refer the following screen for this setup. Mode Setting for >528MB IDE HDD When the IDE hard disk drive you are using is larger than 528MB,please set the HDD mode to LBA mode. Note : Setting incorrect drive mode may make the drive working improperly.

4.3 BIOS Features Setup This setup is designed for customer‘s tuning best performance of the SSC-5x86H board. As for normal operation customers don‘t have to change any default setting.The default setting is pre-setted for most reliable operation. Virus Waring : Enable - Will halt system when any attempt to write to boot sector or patition table of hard disk. Memory Parity Check : Disable - Will not check the DRAM module‘s parity. Right now almost 72-pin SIMM DRAM did not have parity function.

above address,you could enable the shadow to get higher operation performance.When you enable the shadow function,it will also reduce the memory available by between 640KB and 1024KB. 4.4 Chipset Features Setup This setup functions are almostly working for ChipSet(ALI M1489 and M1487). These options are used to change the ChipSet‘s registers. Please carefully change any default setting ,otherwise the system could be running un-stable.

Power Management : This is the master control of all power management functions. The default setting is “disable” for general application. User Defined : Allows user to set any power saving options. Min. Saving : System enters power saving mode after 1 hour no activity. Max. Saving : System enters power saving mode after 5 seconds no activity. PM Control by APM : No - Default setting Yes - System BIOS will wait for APM prompt before it enters any power management mode.

The system will be recovered when the system is re-activity. PM Events : If there is any activity occured on the list of the group,the system will wake up. You can set the IRQ1,IRQ3-15 individually in the list. Appendix A.
